Avaliação de impactos ocasionados pela disposição irregular de resíduos sólidos na localidade Santa Marta, Corrente – PI

Abstract

Establishing a balanced relationship between the generation and treatment of solid waste is a concern that has been extending over the years around the world. This creates the need for effective public policies for the high generation of solid waste and the proper disposal and/or final disposal of these, in order to cause as little damage to the environment and health as possible. One way to study environmental impacts is to understand how human actions affect the processes that occur in socioeconomic systems. The study was developed through field research, with on-site observations in the study area, with the objective of diagnosing and evaluating the situation of the directly affected area in the Santa Marta community, Corrente, Piauí. Regarding the environmental impact assessment method, the Leopold Matrix adapted to the study area was used as a basis to identify and describe the main and possible environmental impacts that occurred with the irregular disposal of solid waste generated by the community, as well as the photographic survey. It was observed that among the main environmental impacts caused in the area are the increase of the erosive process, soil compaction, the emission of greenhouse gas, soil contamination and possible water table, the reduction and stress of local fauna, the reduction of native biodiversity, among others. Thus, based on the studies carried out and data presented here, it is concluded that it is extremely important to implement in the rural area, system of collection, management and proper final disposal of waste as well as make possible the use of recyclable waste. With this measure, it will certainly occur the possible reduction of the environmental impacts mentioned and directs rural communities to a posture of greater social and environmental responsibility.
